Level 1

A methodology for assessing the remaining life of hot reheat steam pipe with longitudinal flaws, such as those typically associated with the longitudinal seam welds, has been developed. The approach uses three levels of analysis. Level 1 employs handbook data, assumed flaw sizes, and design parameters. Level 2 employs handbook data, assumed flaw sizes, and actual operating parameters. Level 3 is tailored to a specific case and uses measured data, inspection results, and actual operating parameters. A computer code was developed to apply this approach to hot reheat steam pipe of 2-1/4Cr-1Mo and 1-1/4Cr-1/2Mo-Si steel. Using data from an EPRI survey (RP2596-7), the results of Level 1 analysis were found to predict the potential for creep damage and fracture and to correlate well with past experience, whereas the traditional lower-bound Larson-Miller approach was generally overly optimistic in predicting remaining service life. The approach predicts creep-crack-growth life and assesses the potential of rapid, unstable fracture occurring before a significant amount of leaking takes place. The usefulness of the methodology is illustrated by means of example analyses of a typical cases that might be expected in service. The parameters that were varied in these analyses include type of material (base metal or weld metal), pressure, temperature, pipe wall thickness, and initial flaw size. The approach provides a preliminary tool to help make inspection, operating, and replacement decisions; but additional work is required to validate it as a general tool.

Midwives are one of the health workers utilizing the MCH (Maternal Child Health) handbook which records the data used to prevent infant, under-five, and maternal mortality. This study aimed to investigate factors related to utilization of the MCH handbook data, namely individual, organizational, and operational techniques. Quantitative approach was used in a cross-sectional survey with a structured questionnaire. Thirty-one  midwives were selected as the sample from Active Alert Village in Temanggung district with rural and urban area representative consideration. Besides, descriptive data were tabulated, and inferential analysis was conducted by Pearson product-moment correlation. Result showed the rate of MCH Handbook data utilization was 78.54%. Also, data requirement perception, data filling skill, motivation, attitudes of midwives and facilities availablity (p < 0.05) are  significantly related. The MCH handbook data utilization was determined by the individual factor, but with no significant relationship to operational and organizational factors except facilities availability.  Therefore, efforts are required to improve data utilization by increasing data requirement perception, data filling skills, motivation and midwives attitudes.
